, My invention relates t6 improvements in medial bend of the doubled plate 19 has an toothed implements, and the object of my, aperture 17 to permit ofqreceiving the angle improvement is to supply a device of this or' bend18 on one of the rods engagingly class which is light, portable, for manual or interlockingly, and the handle and said K 5 use, and in construction devised for superior plate members have alined apertures-to re-- operation under all its conditions of employ 'ceive'abolt 8.secured by a nut 9, the shaft ment. I p of the bolt traversing the hollow of the bend With the foregoing object in view, the ini 18 in a rod 10 to lock the assemblage of rods vention resides in the combination and' .arin engagement with each other between the HI rangement of parts and-in the details of conmembers of said plate, 'sothat none of the struction hereinafter described and claimed, rods are permitted movements relative to it being understood that changes in the prethe plate 19 or .the handle 1 whether lengtlicise embodiment of invention herein 'diswise or rockingly. 1 I a closed can be made within the scope of what The tines or prongs of the device as shown I5 is claimed without departing from the spirit in Fig.1 at 11 are the end portions of said .of the invention; 7 p rods 10 curved toward the crosspiece 2 and I th d. d i Fi 1 is an undivergently passed through the apertures 4 der plan of the devicesof my invention, with. thereof with their free tei minals curved a part of the handle broken" away; Fig. 2 downwardly.

The nected by loops gtoztheend tines on the op- 11o posite face of the flange 3. To supply additional support to the chain when desired,

I use a pair of :bent or curved divergent wire rods 12 having their middle parts passed through apertures 16in the flange 3 and their. ends below said crosspiece pro vided with terminal eyes traversed by the two end tines 10.. The other ends of the rods 12 converge toward the bolt 8, crossing each other, and are secured against the handle by compression of the nut 9, and when the nut is loosened, the rods 12 may be adjusted in position longitudinally along the tines or prongs 10 of the device tosupport the chain 13 in another position. 3

- It should be observed, that the loose -'mountingof' the tines 10 in the apertures 4 together with the yieldab'lc elastic bent or curved parts 15, allow the tines to bend in any direction freely under hard usage, as

the parts 15 give elastically to permit such action without injury to the tines or to an object passed over, yet the curved terminals 11 may holdto the 'surface traversed to gather up loose detritus'and propel it to aplace of collection.

The device as modified and shown in Figs.

' A and 5, preserves the same principles of construction, but the tines are fewer and of heavier wire, so as to be appropriate for use as a hand cultivator. The bends. of the U-shaped tines 10' are seated in bored openings madeslop'ingl in the handle 1 interseating the middle rerf, and which efiectually interclo'cks them as against displace-- ment or rotation. The tines are passed through apertures 16 in the crosspiece flange 3 somewhat spaced from the web thereof to thus tilt the tines as shown in vFig. 5 for better clearance while cultivating.

Having described my invention, whatI claim as hew, ters Patent, is: I

-1. A device of the characterv described, comprising a handle, a plurality of tines and desire to secure by Letconnected intermediately to the handle, and a guiding-bar secured-to thehandle, said thence curved forwardly, a chain connecting device having links loosely mounted upon said tines and movable longitudinally along the tines to vary their spacial relation, and a deformable adjusting device medially connectcd to said handle hack of said guidingharand end-connected-io opposite parts of said chain connecting-device'to hold the latter' in an adjusted position flexibly and 10hgitudinally upon said tines.

3.1K deviceo'f the character described, comprising a handle'having a-longitudinal kerf at one end, a plurality of elastic tines positioned in said kerf intermedlately, all

the tines being bent intermediately with a crim and the tines arranged in contact and para el wlth the said crlmps nested, means .t'or locking said tines as nested tothe handle, and a guiding-bar fixed across the handle, said tines being *curved toward and loosely mounted across the guiding-bar for free longitudinal adjustments at such curved arts and across the guiding barwhen force is applied to the free ends of the tines.
